Received a blood spray from daily

Has anyone else received a blood spray as a daily reward?

I did nexus frenzy today and got the ACE OF SPADES spray from the rewards.

That’s probably the game’s old Supply Drop system acting up, I’ve gotten something similar before out of the blue for a reward after playing a Frenzy match.

It happens whenever you use a class that has no Legendary cards unlocked to complete a map challenge that gives Legendary cards as the reward.
